A few nanoscale adjustments may be all that is required to make graphene-nanotube junctions excel at transferring heat, according to Rice University scientists. The Rice lab of theoretical physicist Boris Yakobson found that putting a cone-like "chimney" between the graphene and nanotube all but eliminates a barrier that blocks heat from escaping.
The research appears in the American Chemical Society's Journal of Physical Chemistry C.

Vanilla aircraft proves to be anything but plain
A DARPA-backed small business effort broke boundaries for long-endurance flight this month by launching a uniquely designed, combustion-powered unmanned aircraft that stayed aloft for more than two days and two nights. The flight was terminated several days ahead of schedule because of incoming weather.
But the craft-built by Vanilla Aircraft of Falls Church, Virginia-landed safely with mo ... more

China Space Plan to Develop "Strength and Size"
China wants to develop "strength and size" in its space program, a China National Space Administration official said last week. In the next five years, the country plans to speed up the development of its space program. China wants to become the first country to carry out a controlled landing of a probe on the far side of the moon in 2018. China also has plans to launch its first probe to the pl ... more

AF looks to ensure cyber resiliency in weapons systems through new office
The Air Force, through its Life Cycle Management Center, has stood up the Cyber Resiliency Office for Weapons Systems (CROWS).
Although the office's primary operating location and senior leadership will be at Hanscom Air Force Base, contributing staff will come from various Air Force organizations and geographic locations. It will focus on integrating activities across the Air Force to ens ... more

Solar storms could spark soils at moon's poles
Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to NASA-funded research. This alteration may become evident when analyzing future samples from these regions that could hold the key to understanding the history of the m ... more

Fractional calculus helps control systems hit their mark
If you've ever searched for ways to curb your car's gas-guzzling appetite, you've probably heard that running on cruise control can help reduce your trips to the pump. How? Cars, it turns out, are much better than people at following what control systems experts call a setpoint - in this case, a set speed across different terrain. But they could be even better.
Calling upon a branch of mat ... more

U.S. Army engineers use 3D printing for small drone
An unmanned aerial vehicle created through on-demand 3D-printing technology has been flight tested by engineers from the U.S. Army Research Laboratory.
The demonstration flight took place at Fort Benning, Ga., last month, the Army said, and was part of the Army Expeditionary Warrior Experiments program to showcase new technology.
"We've created a process for converting soldier mi ... more

Scientists turn memory chips into processors to speed up computing tasks
A team of international scientists have found a way to make memory chips perform computing tasks, which is traditionally done by computer processors like those made by Intel and Qualcomm. This means data could now be processed in the same spot where it is stored, leading to much faster and thinner mobile devices and computers.
This new computing circuit was developed by Nanyang Technologic ... more

Lockheed Martin to build NASA's trojan asteroid explorer Lucy
Lockheed Martin has been selected to design, build and operate the spacecraft for NASA's Lucy mission. One of NASA's two new Discovery Program missions, Lucy will perform the first reconnaissance of the Jupiter Trojan asteroids orbiting the sun in tandem with the gas giant. The Lucy spacecraft will launch in 2021 to study six of these exciting worlds.
The mission is led by Principal Invest ... more

Hong Kong rebel lawmakers met with protests in Taiwan
Pro-China protesters waving placards reading "Independence will get you nowhere" greeted Hong Kong pro-democracy activist Joshua Wong and three rebel lawmakers as they arrived in Taipei Saturday.
Wong, along with Hong Kong legislators Nathan Law, Eddie Chu, and Edward Yiu, is attending a political forum hosted by Taiwan's New Power Party (NPP), which is advocating for recognition of Taiwan ... more

Arecibo Observatory Casts New Light on Cosmic Microwave Background
Arecibo Observatory observations of galactic neutral hydrogen structure confirm the discovery of an unexpected contribution to the measurements of the cosmic microwave background observed by the WMAP and Planck spacecraft.
An accurate understanding of the foreground (galactic) sources of radiation observed by these two spacecraft is essential for extracting information about the small-scal ... more

MIT researchers reveal new technique for measuring gravity
Researchers have found a way to improve atom interferometers, the most common and precise tool for measuring gravity.
Atom interferometers measure difference in wave characteristics between atomic matter. They rely on an exotic state of matter called Bose-Einstein condensates. Researchers in MIT have found a way to improve the precision of atom interferometers by augmenting the condensa ... more

The beating heart of solar energy
The notion of using solar cells placed under the skin to continuously recharge implanted electronic medical devices is a viable one. Swiss researchers have done the math, and found that a 3.6 square centimeter solar cell is all that is needed to generate enough power during winter and summer to power a typical pacemaker. The study is the first to provide real-life data about the potential of usi ... more
